A must-see for companies tackling decarbonization and environmental issues! "Are you struggling with degreasing cleaning?" "Do you want to outsource your cleaning?" Do you have concerns like these?

We explain common cleaning concerns faced by those in the manufacturing industry in a comic format. Our company specializes in contract cleaning, primarily focusing on "contract cleaning" services. We have also built a new factory and can perform "hydrocarbon cleaning" with consideration for the environment. Recently, we have been addressing environmental issues, such as obtaining ISO 14001 certification and installing solar panels on our factory roof, more than ever before. Common concerns include: "I need cleaning for products longer than 4 meters." "I need help because our in-house cleaning capacity is overloaded."

Specialized industrial cleaning service. We accept requests for degreasing of metals, electronic substrates, and more.

At Honma Sangyo Co., Ltd., we have introduced a custom-made large hydrocarbon cleaning system from Japan Field Co., and we use a high-performance hydrocarbon-based cleaning agent called 'NS Clean' for hydrocarbon cleaning solvents. Honma Sangyo's hydrocarbon cleaning machine combines cleaning ability through physical forces and drying capability based on boiling points. It allows for the selection of three types of physical forces: oscillation, rotation, and ultrasound. Due to its superior vacuum drying capability, we perform vacuum drying after steam finishing cleaning. Areas that could not be fully dried due to issues like stop holes and liquid pools with previous cleaning methods can be quickly dried under vacuum conditions, as the boiling point decreases. 【Features】 ○ Compliant with RoHS standards and ISO 14001 ○ Introduction of environmentally friendly hydrocarbon-based cleaning ○ Careful attention is paid to avoid scratches, scuffs, and dents during cleaning ○ Capable of powerful trichloroethylene cleaning ○ Cleaning tests and analysis are also possible For more details, please contact us or download the catalog.

Thank you very much for visiting our company website and catalog, and for your interest in our diesel engine generators. From customer surveys, the most common feedback we received was: - I want to see the actual generators that have been installed. - I want to see them operating under real load. - I want to hear the opinions of companies that have installed them. - I want to see the generators in operation before making a purchase. After all, it’s understandable to feel worried about purchasing a generator without seeing the actual unit first, right? As the saying goes, "Seeing is believing," so we will be holding this tour. It will take place in that area of the Kanto region, where summer temperatures exceed 40°C. We successfully operated our generators this summer as well, so we are confident in handling the heat (sweat). Additionally, it has been confirmed that our generators equipped with the world-leading "Scania engine" are "fuel-efficient." This will surely help reduce daily operating costs. Please note that while we will provide kind and courteous assistance, the meeting and dispersal will be at the site (transportation costs and other expenses will be borne by the customer), so please understand this in advance.

We have introduced Majesta Fragrance at a bar located in Roppongi, enhancing the ambiance with scent. The first impression of a store is greatly influenced by the "fragrance" experienced the moment you enter. The model we introduced is the "MF-01," which costs 8,800 yen per month. Its cylindrical and slim design allows the diffuser to blend seamlessly with the bar's stylish interior without being intrusive. It takes up little space and elevates the adult atmosphere with a high-quality scent. It is chosen by establishments that prioritize the quality of their space, from restaurants to nightlife venues.
